You're right, the compiler will warn about casting the pointer to an
integer of different size, as in
char *Align(char *ptr) {
unsigned low = 0xf & (unsigned)ptr;
return ptr - low + ((low+0xf) & ~0xf);
}
although I think this is actually okay (we are explicitly truncating it
further, and I think it is guaranteed that the truncation preserves the
low byte).
By barf I assume you mean just skip the alignment fix-up.
